God of War: Ascension - Megaera's Parasite

Megaera's Parasites are the weakest enemies in the game and are the first ones encountered. They are small insects, almost resembling scarab beetles the most, that are usually found in groups. Alone, they can attack Kratos, as well as self-destruct. Kratos can grab and kick them, in which they will explode. Later on in the game, various elemental versions are also encountered.

Not too far into the game, they are shown they can infect other living creatures, such as humans and even something as large as one of Aegaeon's hands, essentially controlling them and turning the infected into enemies.
